The Hoss is a 23-litre mountain biking day pack, but would also suit a long commute. Its clever sprung back system is extremely comfortable and airy and its roll-down top keeps the rain out, albeit at the expense of slower cargo access.
There’s plenty of storage space, and main compartment is the fully taped and waterproof. It’s separate from the bladder pocket, so your stuff is very well protected. Considering the price, it should be.
Compression straps keep the load stable so it doesn’t flap around when you’re riding off road. For the weight this pack can handle, we'd prefer to see a wider waist strap for greater stability and improved comfort, though.
There’s also a helmet space and plenty more nooks and crannies for all your tools and gear.
The Dynamic Ventilated Integrated System (DVIS) back support, consisting of eight individually sprung panels, is massively complicated but works extremely well, although it does make the pack a bit heavier.
Over longer distances it’s one of the best, allowing lots of air to your back and distributing weight evenly in conjunction with the comfortable harness.
The load space is a uniform rectangular volume rather than the wedge of the TransAlp, the Hoss’s popular predecessor. Although the waterproofing is great, the roll-down top trades off ease-of-access to the main compartment a little, when compared to top dual-zip entry packs
The bladder is up to Camelbak’s usual high standard and comes with an insulated hose.
